| Buffer overflow in the password management functionality in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted key file. | ||||
| CVE-2016-2516 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service (ntpd abort) by using the same IP address multiple times in an unconfig directive. | ||||
| CVE-2015-1799 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-12 | N/A |
| The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer. | ||||
| CVE-2016-4953 | 5 Ntp, Opensuse, Oracle and 2 more | 15 Ntp, Leap, Opensuse and 12 more | 2025-04-12 | 7.5 High |
| ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. | ||||
| CVE-2016-4954 | 5 Ntp, Opensuse, Oracle and 2 more | 15 Ntp, Leap, Opensuse and 12 more | 2025-04-12 | 7.5 High |
| The process_packet function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (peer-variable modification) by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication. | ||||
| CVE-2016-4957 | 5 Novell, Ntp, Opensuse and 2 more | 9 Suse Manager, Ntp, Leap and 6 more | 2025-04-12 | 7.5 High |
| ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547. | ||||
| CVE-2014-9296 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | N/A |
| The receive function in ntp_proto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets. | ||||
| CVE-2014-9750 | 4 Debian, Ntp, Oracle and 1 more | 7 Debian Linux, Ntp, Linux and 4 more | 2025-04-12 | N/A |
| ntp_crypto.c in ntpd in NTP 4.x before 4.2.8p1, when Autokey Authentication is enabled, allows remote attackers to obtain sensitive information from process memory or cause a denial of service (daemon crash) via a packet containing an extension field with an invalid value for the length of its value field. | ||||
| CVE-2015-7974 | 5 Debian, Netapp, Ntp and 2 more | 9 Debian Linux, Clustered Data Ontap, Oncommand Balance and 6 more | 2025-04-12 | 7.7 High |
| NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key." | ||||
| CVE-2014-9751 | 6 Apple, Debian, Linux and 3 more | 9 Macos, Debian Linux, Linux Kernel and 6 more | 2025-04-12 | N/A |
| The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address. | ||||
| CVE-2014-9295 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | N/A |
| Multiple stack-based buffer overflows in ntpd in NTP before 4.2.8 allow remote attackers to execute arbitrary code via a crafted packet, related to (1) the crypto_recv function when the Autokey Authentication feature is used, (2) the ctl_putdata function, and (3) the configure function. | ||||
| CVE-2015-1798 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-12 | N/A |
| The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC. | ||||
| CVE-2016-4956 | 6 Novell, Ntp, Opensuse and 3 more | 11 Suse Manager, Ntp, Leap and 8 more | 2025-04-12 | 5.3 Medium |
| ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (interleaved-mode transition and time change) via a spoofed broadcast packet. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548. | ||||
| CVE-2016-4955 | 6 Novell, Ntp, Opensuse and 3 more | 11 Suse Manager, Ntp, Leap and 8 more | 2025-04-12 | 5.9 Medium |
| ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service (peer-variable clearing and association outage) by sending (1) a spoofed crypto-NAK packet or (2) a packet with an incorrect MAC value at a certain time. | ||||
| CVE-2014-9294 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | N/A |
| util/ntp-keygen.c in ntp-keygen in NTP before 4.2.7p230 uses a weak RNG seed, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. | ||||
| CVE-2014-9293 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | N/A |
| The config_auth function in ntpd in NTP before 4.2.7p11, when an auth key is not configured, improperly generates a key, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. | ||||
